Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a DVD-integrated television receiver having means for preventing screen burn-in and means for protecting a DVD deck.

[0002] The present invention also relates to a DVD-integrated television receiver having a function of notifying a user that a playback screen can be angle-switched in a television receiver having a built-in DVD deck.

[0003]

2. Description of the Related Art Conventionally, in a DVD-integrated television receiver having a built-in DVD, even if a still image or a DVD menu screen is displayed, until the user releases the still image or selects a cursor in the menu, the user is not allowed to do so. The image was a still image and a DVD menu screen was continuously displayed.

Also, since the power supply of the DVD deck and the power supply of the TV are linked, it is known that the power supply of the DVD deck is always turned on while the power of the TV is turned on.

Conventionally, in order to notify the user that the angle can be switched, a method of turning on an LED or displaying information on a display panel is known.

[0006]

In the case of such a configuration, when an inoperative image such as a still image or a DVD menu screen is displayed for a long time, screen burn-in occurs.

[0007] Also, when the user is watching TV video without using the DVD deck, the DVD deck is turned on.
And the deterioration of the DVD deck is accelerated.

Further, in the case of the conventional configuration for informing that the angle can be switched, the LED or the display panel is hard to be informed to the user watching the television screen and may be overlooked. Parts are required.

[0009]

SUMMARY OF THE INVENTION In order to solve this problem, the present invention provides a method of stopping the playback of a disk or turning on a disk when a video is in a state of no operation such as a still image or a DVD menu screen for a long time. The screen display (hereinafter, referred to as OSD) is moved or the image adjustment value is decreased, and the power supply of the DVD deck is turned off when the DVD deck is not used for a long time.

As a result, the screen burn-in prevention and the DVD
The effect of deck protection is obtained. In addition, the fact that the angle can be switched is displayed on the television screen on-screen, so that the user watching the television screen can be easily understood and the oversight can be notified with few oversights.

At this time, since no LED or display panel is used, the number of components can be reduced and the cost can be reduced.

At 403, a value of 10 minutes is set in the counter, and at 404, the video adjustment flag is turned off. With this configuration, the time is set when the user makes some input, and the counter is decremented at 406 only when the counter is not 0 at 405.
Accurately measured after 0 minutes.

If the counter is greater than 0 at 405,
The counter is decremented at 406, and when the counter is 0 at 405 (1 after the input from the user is lost).
When 0 minute has elapsed), the image adjustment flag is turned ON by 407.

When the video adjustment flag is ON at 408, the video adjustment value is decreased from the current user value at 409, and when the video adjustment flag is OFF at 408, 41
By 0, the video adjustment value is returned to the original user value.

With the above configuration, the user does not attach importance to the TV screen during CD playback, and the
If it continues for more than a minute, the video adjustment value is decreased to prevent the screen burn-in due to the OSD indicating that the CD is being reproduced or the DVD input mode screen.

At this time, if there is any input from the user, the video adjustment value is returned to the original value because the user may give importance to the TV screen.
